Abstract
Athough the clinical efficacy of oncolytic viruses has been demonstrated for local treatment, the ability to induce immune-mediated regression of distant metastases is still poorly documented. We report here that the engineered oncolytic vaccinia virus VVWR-TK-RR--Fcu1 can induce immunogenic cell death and generate a systemic immune response. Effects on tumor growth and survival was largely driven by CD8+ T cells, and immune cell infiltrate in the tumor could be reprogrammed toward a higher ratio of effector T cells to regulatory CD4+ T cells. The key role of type 1 IFN pathway in oncolytic virotherapy was also highlighted, as we observed a strong abscopal response in Ifnar-/- tumors. In this model, single administration of virus directly into the tumors on one flank led to regression in the contralateral flank. Moreover, these effects were further enhanced when oncolytic treatment was combined with immunogenic chemotherapy or with immune checkpoint blockade. Taken together, our results suggest how to safely improve the efficacy of local oncolytic virotherapy in patients whose tumors are characterized by dysregulated IFNα signaling.

Abstract
We report here the successful vectorization of a hamster monoclonal IgG (namely J43) recognizing the murine Programmed cell death-1 (mPD-1) in Western Reserve (WR) oncolytic vaccinia virus. Three forms of mPD-1 binders have been inserted into the virus: whole antibody (mAb), Fragment antigen-binding (Fab) or single-chain variable fragment (scFv). MAb, Fab and scFv were produced and assembled with the expected patterns in supernatants of cells infected by the recombinant viruses. The three purified mPD-1 binders were able to block the binding of mPD-1 ligand to mPD-1 in vitro. Moreover, mAb was detected in tumor and in serum of C57BL/6 mice when the recombinant WR-mAb was injected intratumorally (IT) in B16F10 and MCA 205 tumors. The concentration of circulating mAb detected after IT injection was up to 1,900-fold higher than the level obtained after a subcutaneous (SC) injection (i.e., without tumor) confirming the virus tropism for tumoral cells and/or microenvironment. Moreover, the overall tumoral accumulation of the mAb was higher and lasted longer after IT injection of WR-mAb1, than after IT administration of 10 µg of J43. The IT injection of viruses induced a massive infiltration of immune cells including activated lymphocytes (CD8+ and CD4+). Interestingly, in the MCA 205 tumor model, WR-mAb1 and WR-scFv induced a therapeutic control of tumor growth similar to unarmed WR combined to systemically administered J43 and superior to that obtained with an unarmed WR. These results pave the way for next generation of oncolytic vaccinia armed with immunomodulatory therapeutic proteins such as mAbs.
